Abstract
A method of ink jet printing using an ink jet imaging device including a plurality of nozzles arranged for expelling droplets of an ink by actuation of an ink channel includes the steps of: a) providing a bit map of a spit pattern comprising an arrangement of refresh dots to be printed by each of the plurality of nozzles; and d) printing the bitmap of the spit pattern. The spit pattern includes a plurality of clusters of refresh dots, each cluster including at least two sequential refresh dots expelled from a single nozzle. A spit pattern for use in such a method is disclosed.

A method of ink jet printing using an ink jet imaging device comprising a plurality of nozzles arranged for expelling droplets of an ink by actuation of an ink channel, the method comprising the steps of:
- a) providing a bit map of a spit pattern comprising an arrangement of refresh dots to be printed by each of the plurality of nozzles;
- and
- d) printing a bitmap of the spit pattern,
- wherein the spit pattern comprises a plurality of clusters of refresh dots, each cluster comprising at least two sequential refresh dots expelled from a single nozzle, the at least two sequential refresh dots expelled sequentially from the single nozzle with no dots of the refresh dots being expelled between a first time of the expulsion of a first of the at least two sequential refresh dots and a second time of the expulsion of a second of the at least two sequential refresh dots.
